Sister Wives season 19 premiered recently, and one of the big story lines of the season is about the tenuous relationship between Robyn Brown‘s children and the rest of the Brown family. 45-year-old Robyn was the fourth wife of 55-year-old polygamist patriarch Kody Brown. By the time she joined the Brown family, Kody was already married to Meri Brown, Janelle Brown, and Christine Brown, and had 12 children. In 2010, Robyn and her three children from her first marriage were added to the Brown family mix.
